De Jong, Acton, Gntario, Canada, assignors to Building Products Limited-Montreal, Quebec, Canada Filed Sept. 22, 1961, Ser. No. 140,001 11 Claims. (Cl. Stl-Ztlll) which are of weather and wear resistant material and which will notbecome loose or baggy under varying weather conditions. g

The invention consists essentially in the provision of a weather and wear resistant cover which can readily I understood that the panel cover can be made of any other type of material which will have the desired characteristics, such as lightweight metal. Each panel covering is formed to fit snugly over one face and over the top and bottom horizontal edges of the panel, and is provided with a locking lip extending the full length of its lower horizontal edge and with a horizontal locking recess adjacent thetop horizontal edge of the panel, the locking lip of one panel cover'adapted to engage .with and form a spring tension lock with the locking recess of the panel cover of the 'course of panels immediately below to provide a weathertight seal and to ensure that the covers lie smooth and flat on the underlying panels, and is held tightly at all times against the underlying panel. The invention is further characterized in that the covers are provided witlrcut-outportions along their upper horizontal edges to enable'the siding panels to be secured to a wall without the securing means penetrating the cover. v

The primary object of the invention is to provide a cover for wall siding panels which can be fitted to the panel without additional securing means. V

A further object of the invention is to provide a panel cover which is spring held in interlocking engagement with the covers of adjacent courses of panels.

A further object of the invention is to provide a cover for siding panels in which the spring interlock between adjacent courses forms a weathertight seal. f

A further object of the invention is to provide a building siding which will be weather and wear resistant underthe most severe conditions.

' A further object of the invention is toprovide a building siding in which a cover panel is combined with an insulating siding panel to form a rigid, self-sealing structure having a high insulating value. I

A further object of the invention is to provide a cover for wall siding panels which is free toexpand relative to the underlying siding panel and therefore will main tain a flat andunwrinkled appearance under varying weather conditions such as temperature etc.

-These and other objects ofthe invention will be apparentfrom the following detailed specification and from the accompanying drawings, in which: FIG. 1 is a vertical section of a portion of a wall structure showing one complete course of a wall panel 'ice with its weather and wear resistant covering and fitted in place with the adjacent upper and lower courses.

FIG. 2 is a perspective view of one end of the panel cover before being applied to a wall panel. 7

FIG. 3 is an enlarged sectional view of the upper portion of one panel and the lower portion of the next upper course, with the latter being shown in position before being engaged in weather proof locking engagement therewith.

FIG. 4 is a view similar to FIG. 3 but showing the two panels in locking engagement with each other as in FIG. 1.

FIG. 5 is a partial perspective View of the top portion of a panel similar to FIG. 2 but showing an alternative nailing cut-out.

FIG. 6 is a partial perspective view of the top portion of a panel similar to FIG. 2 but showing an alternative form of interlocking slot.

Referring to the drawings, the panels 5 may be of any type of insulating material such as fibre-board or wood or other boards manufactured from wood of cellular plastics, and are provided with a longitudinal slot or recess 6 on their front face '7, the slot 6 being located near the upper horizontal edge of the panel and in line with the position taken by the lower edge of the panel in the next above course.

Each panel 5 is provided with a weather-proof and wear resistant covering 8 which is preferably made of a plastic material as an extrusion or by a post forming operation, but could be made of light-weight metal. The covering 8 is formed with a channel 9 at its top horizontal edge, with the channel being located to the rear face of the covering, for engagement with the top horizontal edge of the panel 5. The lower horizontal edge of the covering 8 is projected rearwardly at 10 and has a drip head 11 formed on the projection adjacent the front face 12 of the covering, the bead 11 acting as a spring tension device to maintain contact of the portion 10 of the covering against the adjacent edge of the siding panel. The projection 10 terminates in a downwardly and forwardly projected spring'locking member 13 located rearwardly of the rear face of the panel 5. The drip bead 11 may be. provided with perforations llato allow for both moisture vapour and liquid water to escape from the completed wall structure.

Each panel cover 8 is provided with a longitudinally disposed trapezoidal shaped locking recess 14 extending 15 projects upwards to within a short distance of the upper horizontaledge of the recess 14 to provide a longitudinal entrance slot 16 through which the locking member 13 of the panel in the next above course is projected intothe trapezoidal slot to engage with the walls thereof and with the said lip to provide a pressure weatherproof seal between the courses of panels. The top edge of the lip 15 is projected rearwardly at 17 to reinforce the edge of the lip and to provide a shoulder behind which the locking member 13is held in spring sealing engagement.

That portion of the cover 8 located above the'locking recess 14 and designated 12b is provided with a series of longitudinally disposed slots 18 along the length of the cover to permit nailing of the panel board 5 to the wall structure 20 without the nails 21 passing through the cover 8. By nailing directly through the panel, the

relatively pliable cover 8 is not distorted or. drawn by the nail head.

In FIG. an alternative method of permitting nailing of the board 5 to the wall structure 20, is shown. In this form a series of slots 22 are cut through the channel portion 9 at the top horizontal edge of the cover 8.

In FIG. 6 an alternative shape of the locking recess 14 is shown. In this form the slot is of rounded V shape with the rounded portion 23 conforming generally to the rounded portion 24 of the locking member 13 which engages in the locking recess 14.

The rounded portion 23 of the recess 14 provides a spring tension device which, when engaged by the looking member 13 of the adjacent panel cover, will prevent the covers from becoming loose and baggy under varying temperature conditions.

The cover 8, by means of its top longitudinally disposed channel, its locking recess 14 and its rearwardly projecting lower horizontal edge 10 can be securely fitted to the wall panels 5 at any time before installing the panels 5 on a wall surface and can be held thereon without additional securing means. The lower horizontal edge 10 of the cover provides the necessary degree of spring friction required to hold the cover on the panel.

In applying the covered boards to the wall structure 20, a first course of panels is applied and secured by the nails 21. The second course of panels is then applied as follows. Each panel is held in a generally horizontal position relative to the first applied course as shown in FIG. 3. The locking member 13 is then pushed through the slot 16 into the trapezoidal shaped recess 14 and the panel is then pushed upwards and towards the wall structure 20 and is then nailed in place. When the panel is pushed upwards, its lower end makes a solid overlapping contact with the upper end of the covered panel below and the locking member 13 forms a weathertight seal within the recess 14 and behind the lip 15 as shown in FIG. 4. The panel is then secured to the wall structure by the nails 21 which are driven home without contact with the cover 8.

The interlocking of the two panels has the effect of holding the cover 8 solidly and firmly on its panel 5 without drawing or distortion and the initial smooth appearance of the cover is thereby maintained. Furthermore, as the covers are held on their panels by spring tension and not by rigid securing means such as nails etc., they are free to move in all directions without being placed under stress when affected by varying temperature conditions.

What we claim is:

1. A building siding in combination, a wall structure,
